Description

Technical Field

[0001] This invention relates to the field of connector assembly equipment technology, and in particular to a pin separating mechanism and a pin insertion device. Background Technology

[0002] In electronic products, pin insertion equipment, also known as a pin insertion machine, is used for inserting pins into various coil frames, connectors, and other plastic parts that require pins. It boasts advantages such as simple operation and high efficiency, making it a highly practical piece of mechanical production equipment for the electronics industry. Connectors consist of plastic parts and pins, used to transmit current or signals.

[0003] Currently, PIN pins need to be separated before being inserted into the pin socket to make the messy PIN pins orderly. After being separated, the PIN pins are inserted into the pin socket in sequence. The process of separating the PIN pins and inserting them into the pin socket mainly relies on manual operation. Manual operation is slow, cannot be automated, and is prone to mechanical damage. Summary of the Invention

[0004] The main objective of this invention is to provide a pin-separating mechanism that addresses the technical problem of slow production efficiency caused by the reliance on manual operation in the current pin-separating process for PIN connectors.

[0006] Delivery assembly for delivering pins;

[0007] Transition components for securing the pins; and

[0008] The needle assembly includes a support plate and a pressure plate. The delivery assembly delivers the needle to the support plate. The support plate is provided with a first driving member, which drives the pressure plate to move toward the support plate to clamp the needle. The support plate is connected to a second driving member, which drives the support plate to move toward the transition assembly to insert the needle into the transition assembly.

[0009] Optionally, the conveying assembly is provided with a conveying track, and the pin moves along the conveying track;

[0012] Optionally, the support plate has an initial position flush with the conveying track, a pin position for driving the pin to insert into the transition assembly, and a clearance position away from the pin;

[0013] The second driving member has a fixed end and a driving end. The driving end is connected to the support plate and drives the support plate from the initial position to the pin position. The fixed end is connected to a fourth driving member, which drives the support plate from the pin position to the avoidance position.

[0014] Optionally, a sensor is provided at one end of the conveying track near the support plate, the sensor being used to sense the pins conveyed to the support plate.

[0015] Optionally, the transition component includes a receiving platform with at least one socket for receiving the pin. The receiving platform is connected to a movable base, and the movable base is connected to a movable module, which drives the movable base to move.

[0016] Optionally, the receiving platform is slidably connected to a limiting plate, and the limiting plate is connected to a fifth driving member.

[0017] Optionally, the conveying assembly further includes a vibratory feeder, the conveying track is connected to the vibratory feeder, the pin is conveyed from the vibratory feeder to the conveying track, and a straight vibrator is provided at the bottom of the conveying track.

[0020] The technical solution of this invention uses a conveying assembly to transport inserts. The needle assembly includes a support plate and a pressure plate. The support plate is used to receive the inserts transported by the conveying assembly. A first driving member drives the pressure plate to move toward the support plate to clamp the inserts.

[0033] This invention proposes a dispensing mechanism.

[0034] In the existing technology, the PIN needles need to be separated before being inserted into the needle socket to make the messy PIN needles orderly. The separated PIN needles are then inserted into the needle socket in sequence. The process of separating the PIN needles and inserting them into the needle socket mainly relies on manual operation. Manual operation is slow, cannot be automated, and is prone to mechanical damage.

[0035] To solve the above-mentioned technical problems, the technical solution of the present invention adopts a conveying component to transport the insert. The needle assembly includes a support plate and a pressure plate. The support plate is used to receive the inserts transported by the conveying component. A first driving member drives the pressure plate to move toward the support plate to clamp the inserts. A second driving member drives the support plate to move so that the clamped inserts are inserted into the transition component. In this way, the automatic transport and automatic insertion of the inserts into the transition component can be realized, thereby realizing the automatic needle separation of the inserts without relying on manual operation and improving production efficiency.

[0036] The above technical solution will be described in detail below with reference to the accompanying drawings.

[0037] In embodiments of the present invention, such as Figure 1-4 As shown, the minute hand mechanism includes:

[0038] Conveyor assembly 100 is used to convey inserts;

[0039] Transition component 200, used to secure the pin; and

[0040] The needle assembly 300 includes a support plate 310 and a pressure plate 330. The conveying assembly 100 conveys the needle to the support plate 310. The support plate 310 is provided with a first driving member 340, which drives the pressure plate 330 to move toward the support plate 310 to clamp the needle. The support plate 310 is connected to a second driving member 320, which drives the support plate 310 to move toward the transition assembly 200 to insert the needle into the transition assembly 200.

[0041] In practical implementation, the pin sorting process involves organizing a number of disordered pins into a single or multiple ordered group, making them easier to insert into the pin holder for smooth injection molding. The conveying assembly 100 can be a conveyor belt or a vibratory feeder 140, etc., capable of conveying the pins to the support plate 310. The pins can be of various shapes; of course, it is understood that a suitable conveying assembly 100 can be selected based on the shape of the pin. The transition assembly 200 has insertion holes 211 that mate with the pins to accommodate and fix them. The transition assembly 200 conveys the pins to the corresponding positions for the next process. In this embodiment, an L-shaped pin is used as an example.

[0042] In this embodiment, the conveying assembly 100 conveys the pin to the top surface of the support plate 310. Since the pin has an L-shaped structure, it includes a clamping portion and an insertion portion. The clamping portion is located on the support plate 310, and the insertion portion extends out of one side of the support plate 310 and faces downwards. Further, in this embodiment, the support plate 310 includes a connecting plate 311 and a carrying plate 312. The first driving member 340 and the second driving member 320 are connected to the connecting plate 311. The carrying plate 312 is disposed close to the conveying assembly 100. The conveying assembly 100 conveys the pin to the carrying plate 312, and the pressure plate 330 cooperates with the carrying plate 312 to clamp the pin. The connecting plate 311 is located on one side of the transition assembly 200, and the carrying plate 312 is located on the side of the connecting plate 311 close to the conveying channel, with its top surface flush with the conveying channel, allowing the pin to be smoothly conveyed onto the carrying plate 312. One side of the support plate 312 extends toward the transition assembly 200, thus creating a clearance space between the support plate 312 and the side wall of the connecting plate 311 facing the transition assembly 200, facilitating the movement of the transition assembly 200. Furthermore, the support plate 312 is also provided with a baffle located on the side of the support plate 312 away from the conveyor track 110, which can prevent the pin from falling off the support plate 312. In addition, the height of the baffle is less than the thickness of the pin, ensuring that the pressure plate 330 can properly press the pin.

[0043] The pressure plate 330 is located above the support plate 310. The first driving member 340 and the second driving member 320 are driven by cylinders, hydraulic cylinders, or motors. In this embodiment, cylinders are used as an example. In addition, the third driving member 130, the fourth driving member 400, and the fifth driving member 241 also adopt cylinder structures. Specifically, the first driving member 340 is fixed to the side wall of the support plate 310. The telescopic rod of the first driving member 340 is connected to the pressure plate 330. The initial state of the telescopic rod of the first driving member 340 is the extended state. When the needle is delivered to the support plate 310, the first driving member 340 drives the telescopic rod to retract, so that the pressure plate 330 above the support plate 310 presses down and presses the needle tightly onto the support plate 310. In this way, the support plate 310 and the pressure plate 330 clamp the clamping part of the needle. The telescopic rod of the second driving member 320 is connected to the support plate 310. The initial state of the telescopic rod of the second driving member 320 is also extended. The second driving member 320 drives the telescopic rod to retract, causing the support plate 310 to move downwards. Simultaneously, the support plate 310 also drives the first driving member 340 and the pressure plate 330 to move synchronously. Thus, as the second driving member 320 drives the support plate 310 downwards, the insertion part of the insert pin is inserted into the transition component 200, achieving the transfer of the insert pin to the transition component 200. It is understandable that the transition component 200 is located within the travel range of the insert pin's insertion part, allowing the insert pin to be smoothly fixed on the transition component 200, completing the transfer of the insert pin.

[0044] Optionally, the conveying assembly 100 is provided with a conveying track 110, along which the pin moves;

[0045] A third driving member 130 is provided on the conveying track 110. The third driving member 130 is connected to a pressure block 120. The third driving member 130 drives the pressure block 120 to move toward the conveying track 110 to press the insert pin.

[0046] In the specific implementation process, the conveying assembly 100 conveys the pins to the support plate 310 via the conveying track 110. The support plate 310 is located at one end of the conveying track 110. It can be understood that the conveying track 110 has a space for the pins to pass through. The pins move along the conveying track 110 to the support plate 310. The support plate 310 can only hold one pin at a time. Since the conveying track 110 does not stop conveying, subsequent pins will affect the previous pins. Therefore, in this embodiment, a third driving member 130 is provided on the conveying track 110. The telescopic rod of the third driving member 130 is connected to the pressure block 120. The initial state of the telescopic rod of the third driving member 130 is the retracted state. There is a gap between the pressure block 120 and the conveying track 110, so that the pins can pass through the gap smoothly for conveying. After a pin is delivered to the support plate 310, the third drive unit 130 is activated, driving the telescopic rod to extend, causing the pressure block 120 to press against the conveying track 110, pressing the pin firmly onto the conveying track 110, preventing the pin from continuing to be delivered forward and interfering with the pins on the support plate 310.

[0047] Furthermore, a protrusion 121 is provided on one side of the pressure block 120. The protrusion 121 is used to press the pin located on the support plate 310. The pressure plate 330 is provided with a groove 331 that mates with the protrusion 121, and the protrusion 121 is accommodated in the groove 331. Specifically, the protrusion 121 is provided on the side of the pressure block 120 facing the pressure plate 330 and close to the conveying track 110, so that it can smoothly press the pin on the support plate 310. The protrusion 121 moves synchronously with the pressure block 120. Furthermore, the protrusion 121 and the pressure block 120 are integrally set, and the length of the pressure block 120 extending beyond the length of the protrusion 121 is sufficient to smoothly press the pin. The pressure plate 330 has a recessed groove 331 on one side facing the pressure block 120. The protrusion 121 moves in the groove 331, so that the pressure plate 330 can avoid the protrusion 121 and smoothly press the pin on the support plate 310. When the support plate 310 drives the pin to move, it also cooperates with the pressure plate 330 to keep the pin in a clamped state.

[0048] Optionally, the support plate 310 has an initial position flush with the conveyor track 110, a pin position for inserting the drive pin into the transition assembly 200, and a clearance position away from the pin.

[0049] The second driving member 320 has a fixed end and a driving end. The driving end is connected to the support plate 310 and drives the support plate 310 from the initial position to the pin position. The fixed end is connected to a fourth driving member 400, which drives the support plate 310 from the pin position to the avoidance position.

[0050] In the specific implementation process, the driving end of the second driving member 320 is a telescopic rod. The initial state of the telescopic rod is the extended state. After the pressure plate 330 presses the pin, the driving end retracts, causing the support plate 310 to move downward and driving the pin downward to insert into the transition assembly 200. The telescopic rod of the fourth driving member 400 is connected to the fixed end of the second driving member 320. The initial state of the telescopic rod of the fourth driving member 400 is the extended state. After the support plate 310 inserts the pin into the transition assembly 200, the telescopic rod of the first driving member 340 extends and resets, causing the pressure plate 330 to leave the pin. The telescopic rod of the fourth driving member 400 retracts, driving the support plate 310 to continue moving downward and leaving the support plate 310 away from the pin. It can be understood that the stroke of the first driving member 340 driving the pressure plate 330 to move upward is greater than the stroke of the fourth driving member 400 driving the support plate 310 to move downward, to avoid the pressure plate 330 contacting the pin. After the pressure plate 330 and the support plate 310 leave the pin, the transition assembly 200 is displaced.

[0051] Optionally, a sensor 500 is provided at one end of the conveying track 110 near the support plate 310. The sensor 500 is used to sense the pins conveyed to the support plate 310.

[0052] In this embodiment, it is understood that the needle dispensing mechanism is equipped with a control system, and the sensor 500 is communicatively connected to the control system. Specifically, one end of the conveying track 110 has a through hole on the side that avoids the pressure plate 330 and the support plate 310. The sensor 500 is fixed in the through hole, which is opposite to the support plate 310. When the needle is conveyed to the support plate 310, the sensor 500 senses the needle and generates a signal that is transmitted to the control system. The control system controls the third driving member 130 to press down the pressure block 120 to press down the needle according to the signal. The first driving member 340 presses down the pressure plate 330 to press down the needle. The second driving member 320 presses down the support plate 310 to insert the needle into the transition component 200. The first driving member 340 lifts the pressure plate 330. The fourth driving member 400 moves the support plate 310 downward. After the transition component 200 is moved, the fourth driving member 400 and other driving members are reset to their initial state, ready for the next needle insertion.

[0053] Furthermore, the transition component 200 includes a receiving platform 210, which has at least one insertion hole 211 for receiving a pin. The receiving platform 210 is connected to a movable base 220, which is connected to a movable module 230. The movable module 230 drives the movable base 220 to move.

[0054] In this embodiment, the moving module 230 adopts a screw-slider module or a sliding cylinder module, etc., and is not limited in this embodiment. The moving module 230 drives the moving base 220 to slide. A receiving platform 210 is fixed on the moving base 220. The top surface of the receiving platform 210 near the connecting plate 311 protrudes upward, and a plurality of insertion holes 211 are sequentially opened along its moving direction for accommodating the insertion pins. Furthermore, the stroke of the moving seat 220 moving towards the conveying component 100 is the return stroke, and the stroke moving away from the conveying component 100 is the outward stroke. The pin is first inserted into the socket 211 away from the conveying component 100, and then the moving seat moves in the outward stroke direction to shift, and then the pin is inserted into the next socket 211, until all sockets 211 are filled with pins. Then the moving module 230 drives the moving seat 220 to move the receiving table 210 away from the conveying component 100, waiting for the pin to be collected for the next process. After the pin is collected, the moving module 230 drives the moving seat 220 to return the receiving table 210, preparing for the next pin insertion process.

[0055] Furthermore, the receiving platform 210 is slidably connected to a limiting plate 240, and the limiting plate 240 is connected to a fifth driving member 241. The fifth driving member 241 drives the limiting plate 240 to approach the pin, so as to adjust the orientation of the end of the pin away from the socket 211.

[0056] In the specific implementation process, the fifth driving component 241 is connected to the receiving platform 210. The limiting plate 240 is an L-shaped plate, with one end sliding on the receiving platform 210 and the other end extending towards the direction of the insertion hole 211. After the insertion holes 211 are all inserted with pins, the fifth driving component 241 drives the limiting plate 240 to move towards the insertion hole to press the insertion hole. Furthermore, the receiving platform 210 is provided with spaced placement grooves, which correspond to the insertion holes. After one end of the insertion hole 211 is inserted, the other end extends out of the receiving platform 210 along the placement groove. The limiting plate 240 also serves to ensure that the insertion holes are aligned, guaranteeing the positional accuracy of the insertion holes during retraction.

[0057] In addition, in this embodiment, the conveying assembly 100 also includes a vibratory plate 140, the conveying track 110 is connected to the vibratory plate 140, the pin is conveyed from the vibratory plate 140 to the conveying track 110, and the bottom of the conveying track 110 is provided with a straight vibrator 150.

[0058] The present invention also proposes a pin insertion device for inserting pins into a pin holder. The pin insertion device includes a robotic arm and a pin separating mechanism as described in the above embodiments. The robotic arm grips the pins on the transition assembly 200 and inserts them into the pin holder. The specific structure of the pin separating mechanism is as described in the above embodiments. Since this pin insertion device adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0059] In the specific implementation process, after the moving module 230 of the pin distribution mechanism transports the pins on the receiving platform 210 to a position close to the robot arm, the fifth driving component 241 drives the limiting plate 240 to reset. The robot arm then grips one or more sets of pins on the receiving platform 210. Of course, a set of pins can include one or more pins, depending on the actual product. After the robot arm grips the pins, it inserts each set of pins into the pin holder at a time. The pin holder is then driven to the injection molding machine for injection molding, thus completing the pin injection molding process of the connector. The entire process is automated, eliminating the need for manual operation and avoiding mechanical damage. Automated pin insertion can improve production efficiency and product yield, and save costs.

[0060] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
